Civil libertarians say this week's far north Queensland abortion trial has highlighted major deficiencies in the law.

A Cairns jury yesterday found Tegan Leach, 21, not guilty of procuring her own miscarriage and Sergie Brennan, 22, not guilty of unlawfully supplying drugs to procure an abortion.

The State Government says it has no plans to decriminalise abortion.

But Queensland Council for Civil Liberties president Michael Cope says it is clear changes need to be made.

"Even in the ... bad old days, the police didn't charge the woman because they'd obviously accepted that the woman had been through enough already," he said.

"These charges were just astonishing and so far as we are concerned they should never have been proceeded with."

Mr Cope says the Law Reform Commission should tackle the issue if the Government will not.

"If they don't want to lead it they can do what the Victorian Labor government did and get the Law Reform Commission to conduct a public inquiry or a public consultation process and produce some recommendations based on their soundings in the community," he said.

'Bill would fail'

Queensland Premier Anna Bligh said while she supports decriminalisation the majority of MPs do not, which means a conscience bill would fail.

Ms Bligh also says such a vote could actually lead to more restrictions.

"We run the risk that we could in fact see it amended and access to these services restricted further than they are now," she said.

"This is not something to do lightly, it's not something to do just because people want to have a public debate.

"If you don't have a high degree of confidence that it would be supported you could in fact make things worse and that is why I'm cautious."

Reproductive Choice Australia spokeswoman Dr Leslie Cannold says that is not good enough.

"I don't take any notice of the claims that there are not numbers in the Parliament for change," she said.

"There is no bill for people to have a view on whether or not they would vote for or against it.

"That's just something politicians say as a way of excusing themselves for inaction."

Liberal National Party (LNP) frontbencher Tim Nicholls says the Opposition does not want to change the law.

"It is a very difficult and complex issue because it involves matters of moral belief and religious belief and a whole range of spectrums that take it to an extent outside of the normal political consideration," he said.

"That makes it very difficult for all of us as MPs to be able to reconcile those issues.

"The view of the LNP is that there is no need to change, the existing law is adequate to deal with the issues."

'Abortions available'

Deputy Premier Paul Lucas says it is wrong to suggest abortions are not available in Queensland.

He says the case was not about abortion, but about administering a drug.

"Even in a regime where you had abortion without restriction you would still have a regime that would prosecute people who were not qualified to either order the drugs or administer the drugs or a surgical procedure," he said.

"You have to do that as a protection against everybody and frankly there are 10,000 abortions a year performed in Queensland.

"It is wrong to suggest they are not available in Queensland, they are available in accordance with the law."
